Iceland has several volcanoes and is situated on two tectonic plates – the North American plate and Eurasian plate.
The volcano -Eyjafjallajökull- situated on the Eastern Volcanic zone in southern Iceland, began erupting lava on 20 March 2010. At first there was not much explosive activity. A second eruption then began beneath the ice cap near the summit of the volcano on 14 April. This eruption caused the melting of large amounts of ice, leading to flooding in southern Iceland.
